What Firewalls Do & Donot Do
2008-03-28 15:01:00 Over the last few years, security threats have grown and altered dramatically and so have the defences. Traditional firewalls, installed over three years ago, are often not best suited for current threats and don?t protect against a number of newer threats.

Use of Firewalls On internet
2008-02-05 09:03:00 In this day, when broadband and LAN/Cable Internet access is rampant, there is always a chance that somemay may break into your computer, gain access and control your computer to do malicious acts without your permission. A firewall acts like a filter for the data that's going in and out of your computer. If it detects that a program is trying to access the Internet or your local network without your permission, it will stop such activity. Also, if a hacker or any other user tries to gain access to your computer without your permission, it will block all such activity too. The Windows Firewall that comes bundled along with Windows XP SP2 is woefully inadequate when it comes to protecting your computer.The key to running a firewall efficiently is to configure it right. When it comes to configuring, the key steps to remember are these:a) If you do not know the program, deny it access to the Internet and the local network.b) Never allow the software to "remember" the access rights for...

Understanding Firewalls - By Amol Wagh
2007-12-09 05:02:00 What is a Firewall?A firewall is a tool that monitors communication to and from your computer. It sits between your computer and the rest of the network, and according to some criteria, it decides which communication to allow, and which communication to block. It may also use some other criteria to decide about which communication or communication request to report to you (either by adding the information to a log file that you may browse whenever you wish, or in an alert message on the screen), and what not to report.What Is It Good For?Identifying and blocking remote access Trojans. Perhaps the most common way to break into a home computer and gain control, is by using a remote access Trojan (RAT). (sometimes it is called "backdoor Trojan" or "backdoor program". Many people simply call it a "Trojan horse" although the term "Trojan horse" is much more generic). A Trojan horse, is a program that claims to do something really innocent, but in fact does something much less innocent. T...

A firewall is a system or a group of systems which guard a trusted network( The Internal Private Network from the untrusted network (the Internet.)

tcptraceroute, A way to make traceroutes with firewalls in the middle of th
2007-09-03 03:19:00 Introduction Today I want to show you a real good network administration tool, if you do network administration, you should use ping and traceroute to check whenever a host is alive or not. Maybe the steps of testing is first ping the server, and if there is no response, you try with traceroute to see where in the route an interruption exists. Traceroute works sending ICMP packets to all the routers in the way to the destination host, but these days more and more routers and server have the ICMP packets filtered, so here is where tcptraceroute comes to save the day. As you may guess from its name tcptraceroute is like traceroute but sends tcp packets instead of ICMP packets thus avoiding the filtering of the packets in the route. Installation Debian / Ubuntu apt-get install tcptraceroute Fedora / Centos Be sure to have Dag Wieers repository enabled and then run: yum install tcptraceroute Usage tcptraceroute [-nNFSAE] [ -i interface ] [ -f first ttl ] [ -l length ] [ -q number of qu...

Bypass workplace firewalls: SSH tunneling for dummies
2007-05-08 15:04:00 Franck from Franck's Place posted an excellent how-to some time ago on his blog. Specifically, he provides instructions on how to surf freely at work an bypass idiotic web surfing restrictions. I have quoted Franck's introduction, but will leave you to click the link to view the post in its entirety on Franck's blog.SSH tunneling for dummies"More and more, litigation and regulation is forcing companies to restrict what you can do on an office computer. For some people it's now easier to work from home than the office because of those constraints. The irony is that most people also have handheld devices with none of those constraints anyway. And even without any of those, it's very easy to bypass most protection systems.For example, here is a way to bypass a corporate firewall that prevents you to access certain websites -- not that you should or want to do it. If you follow those steps, you do it at your own risk! But here it is, for educational purposes :)"SSH tunneling for ...

Network Access Control and Check Point Firewalls

The company said version R65 includes performance enhancements that speed packet inspection throughput, as well as adding additional management features.NAC is also a key part of the new release."The most successful security product ever is likely the firewall and so far it's not involved in NAC," Bill Jensen, product marketing manager at Check Point, told internetnews.com.

Hardware Versus Software Firewalls
2007-02-23 06:34:03 According to estimates, an unprotected Windows computer system connected to the Internet could be compromised within twelve minutes. In light of this, the need for computer security has expanded in the last few years. Today, it is just as necessary for home users to secure personal computers as it is for businesses to secure office computers. In order to gain security benefits like those many businesses possess, home network security often utilizes the same models. The difference, however, has been that most home users do not have the financial resources for top of the line security equipment. This has led many home users to begin using security tools such as freeware firewalls and over-the-counter hardware firewall solutions. This raises a question. How do the freeware firewalls compare to expensive, all-in-one firewall solutions such as the Cisco PIX? The goal for this project, then, is to compare the Cisco PIX with two freeware firewalls.

Online Safety - Firewalls
2006-12-27 04:23:02 This is just a quick reminder that in view of the present holidays, when you make purchases online you MUST protect yourself as much as possible. Using a FireWall and anti-virus programs on your computer can help to prevent unauthorised access to information on your computer (reference: Antivirus Programs). Also ensure that you have spam suppressers installed and anti-adware software, both of which can contain dangerous viruses and codes.It is also best to use payment processors instead of sending your Credit Card information over the internet everytime you make a transaction (reference: Online Payment Processors). This helps you to keep your number seucure and less likely to be hacked.By all means, clear your browser cookies before you close your browser. In addition, clear your temporary internet files folder regulary. You can never be too careful.
Skype certifies McAfee virus scan and firewalls
2006-08-06 18:48:38 Skype and McAfee inked an interesting deal lately. McAfee Security Suite 2006, McAfee VirusScan 2006 and McAfee Personal Firewall 2006 are now optimized for Skype VoIP calling application. “The two software products do not directly link up, a Skype representative said,” adds CNet. “However, Skype conducted tests to the effectiveness of McAfee’s protection of the desktop while its voice over Internet Protocol software was is use. For example, a McAfee product can scan files before they are transferred during a call.” Such a move change nothing to Skype’s opacity to network administrator. But does give enough security level to Skype to break deeper into the small and medium business market. Which Skype is eager to do.
